John, as I said earlier, something arose which is temporarily making it difficult to add to this discussion. However I can add that my data were not intended as an example of how to predict earthquakes. They were largely to show that they are not always random events. And that means that there is some chance that occurrence times for some of them can be organized into different higher and lower probability time windows. That is a type of early step in the prediction process.

Roger is one of our bulletin board probably calculation experts. Perhaps he will eventually join in the discussion.
